Jonas Gutierrez moved back to Defensa y Justicia last month.
The former Newcastle favourite still playing league football in Argentina after spending last season with Independiente.
The now 35 year old has played a handful of league and cup games since rejoining the club on the 12th of July.
On Tuesday night Defensa y Justicia faced Banfield in the first leg of the Copa Sudamerica final (the game ended 0-0).
Only 10 minutes into the game Jonas Gutierrez suffered a ‘chilling injury’ according to one report in the Argentine media.
The winger is said to have simply ‘stepped badly’ rather than a bad tackle, the freak injury seeing him collapse to the ground in obvious agony.
Reports detailing that the kneecap on his left leg was able to move.
Jonas’ club then later confirmed that the injury was believed to be a rupture of the patella tendon.

There is no date given yet for when he may return but it is so serious that at the very least it will be into 2019 before the former Argentine international might return.
By then he will be approaching his 36th birthday, maybe leaving it in the balance as to whether he will play at that level again.
Hopefully he can and as always, best wishes to Jonas Gutierrez on his recovery.
